AUXILIARY AIR-SUPPLY FOR INTERNAL-COMBUSTION ENGINES.

Specification of Letters Patent.

Patented Aug. 12, 1919.

Application filed July 16, 1917. Serial No. 180,888.

To all whom it may concern:

Be it known that I, JOHN J. Gooorr, acitizen of the United States,residing at Benton, in the county of Marshall and State of Kentucky,have invented certain new and useful Improvements in Auxiliary Air-Supplies for Internal-Combustion Engines,-

of which the following is a specification, reference being had to theaccompanying 1o drawings.

This invention relates to internal combustion engines, and particularlyto means for introducing auxiliary air into the intake manifold of anengine.

The general object of the invention is the provision of means wherebyheated auxiliary air may be introduced into the intake manifold to mixwith the fuel charge therein, thus putting the fuel charge into betterworking condition and increasing the power which may be obtained fromthe engine.

A further object in'this connection is to provide means whereby theamount of auxiliary air may be regulated and whereby the air may beheated by the exhaust of the engme.

A further object is to provide means whereby the engine may be primed torender starting easier in cold weather and whereby kerosene may beintroduced while the engine is hot and running for the purpose ofblowing out the carbon which may accumulate on the cylinder walls.

Other objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawings, wherein Figure1 is a side elevation of a portion of an automobile, the dashboard beingin section and showing my device as applied thereto;

Fig. 2 is a fragmentary side elevation of the construction illustratedin Fig. 1 to show the manner of supporting the pipe 13;

Fig. 3 is a fragmentary section of the pipe 12 and a portion of the pipe15.

Fig. i is a perspective view of the clamp for supporting the pipe 13.

Referring to these drawings, 10 designates the several cylinders of aninternal combustion engine of any ordinary type, and 11 the intakemanifold thereof, 12 designating the exhaust manifold. All of theseparts are constructed or arranged in any usual or ordinary manner. Myattachment comprises a pipe 13 which opens into the intake manifold 11and extends upward therefrom and carries at its upper end the T 14. Fromone end of this T extends a pipe 15, which passes through the dash board16 of a car and then 0 extends downward and extendsthrough the exhaustpipe 12. This pipe 15 is formed with a coil 17 and is also provided onthe lnner face of the dash board or instrument board 16 with a "alvecasing 18, havinga valve'19, whereby the flow of hot air passing fromthe exhaust manifold 12 may be carried to the intake manifold. Theopposite end of the T is connected to a pipe 20, which extends to theinner face of the dash board or instrument board and then extends upwardand is provided with a priming cup 21 controlled by the usual valve 22.The pipe 13 is held in upright position by means of a clamp 23, one endof which is engaged by one of the engine bolts.

In the practical use of this invention, the air entering the pipe 15 isheated by the exhaust and this hot air is drawn into the intake manifoldupon the suction stroke of the piston and mixed with the charge comingfrom the carbureter, and from thence passes into the several cylindersin the usual manner. Inasmuch as this auxiliary air is heated, thegasolene or other fuel which has passed into the intake manifold is morehighly vaporized and forms a more combustible and powerful gas, whichwill secure a maximum eX- plosive effect in the cylinders of the enginewith a minimum amount of fuel. Thus increased mileage per gallon of fuelis secured. The amount of the air is regulated by the shut-off cock orvalve 19, which is preferably arranged so as to secure a relatively widerange of regulation. By the use of the priming cup, gasolene may be usedin the manifold at the same time that hot air is reduced and thus securean easy starting of the machine, even in cold weather-and kerosene mayalso be vaporized by passing with the hot air into the intake manifold,thus cleaning out carbon.

It is to be noted that by the construction above described, I providemeans whereby either cold air or hot air may be drawn into the inletmanifold 11. Thus if the valve 19 be closed and the valve 22 be opened,cold air may be drawn into the manifold and if, on the other hand, thisvalve 22 be closed and the valve 19 opened, hot air will be drawn intothe manifold and obviously if both valves be closed, the supply ofauxiliary air will be cut off.

While I have illustrated a certain definite arrangement of thestructure, I Wish it understood that various minor changes may be madein the details of construction and arrangement of parts, Withoutdeparting from the spirit of the invention.

Having described my invention, What I claim is r The combination with aninternal combustion engine, provided with an intake manifold and anexhaust manifold, of a pipe opening at one end into the intake manifold,a T connected to the other end of said pipe, an air inducting pipeconnected at one end to one branch of said T and leading rear- Wardlytherefrom and then vertically downward and having its other end open andex- 1 tending through the exhaust manifold and provided intermediate ofits ends with a, controlling valve, said vertically extending portion ofthe conducting pipe having a coil to take up vibrations in said pipe,and another pipe connected at one end to another branch of the T, saidlast named pipe being provided at its opposite end with a valved primingcup, 'as and for the purpose set forth.

In testimony whereof I hereupon afiix my signature in the presence oftwo Witnesses.
